Bioavailability of Mercury Discharges
Water Environment Research Foundation
Project
Highlights
- Developed Methylation Tool to identify site-specific conditions.
- Project for the Water Environment Research Foundation (WERF).
PROJECT GOALS, ACHIEVEMENTS, AND BENEFITS
McGovern McDonald Engineers (MME) assisted the Water Environment Research Federation (WERF) with assessing the methylation potential and bioavailability of mercury discharged from point sources into receiving waters, with a focus on the San Francisco Bay. MME helped to develop a tool to help dischargers assess this potential for site-specific conditions. (Estimation of Mercury Bioaccumulation Potential from Wastewater Treatment Plants in Receiving Waters, 05-WEM-1CO).
Development of a Low Impact Development (LID) Life Cycle Cost Benefit model that determines the costs and benefits of stormwater measures to both the customer and for the SFPUC.
Assessed the methylation potential and bioavailability of mercury discharged from point sources for the Water Environment Research Federation (WERF).
Identified stormwater and recycled water cost and benefits to the customer and SFPUC with implementation of LID techniques.
Development of stormwater best management practice O&M life cycle costs for street installation as part of the San Francisco Better Streets Plan.
Provided NPDES regulatory and permitting support for treated wastewater and stormwater discharges and Combined Sewer Overflows (CSOs) to the Bay and Pacific Ocean.
Development of a modeling tool for States and NPDES permit holders to assist nutrient management strategies for the Water Environment Research Federation.
Reviewed NPDES stormwater documents for transfer from private to SFPUC authority and recommended future monitoring program improvements for the SFPUC’s Mission Bay Development.
